From the article: “In particular, five fundamental attributes of social media have harmed society. AI also has those attributes. Note that they are not intrinsically evil. They are all double-edged swords, with the potential to do either good or ill. The danger comes from who wields the sword, and in what direction it is swung. This has been true for social media, and it will similarly hold true for AI. In both cases, the solution lies in limits on the technology’s use.”
But a time travel capable society per the above comment?
I mean, until it happened it’s just a fiction. Maybe time travel wasn’t possible at all until we nuked ourselves back to the stone age fighting over what was left after climate change.
